BepiColombo: The Story of a Highly Ambitious Mission
Mercury. The planet closest to the Sun. It remains highly mysterious to us. Only two space probes have explored it: Mariner 10, which flew by three times in 1974-75, and then MESSENGER, which orbited the planet’s poles from 2011 to 2015. Both missions were highly innovative and represented pioneers in space exploration. Unfortunately, neither fully…

SAOCOM 1A: an Argentine observation satellite and supersonic booms in California.
If there’s one thing we’re starting to get used to, it’s the spectacular landings by SpaceX. These were typically done at three distinct locations: on land at Cape Canaveral, in the Atlantic on the OCISLY barge, or in the Pacific on the JRTI barge.

A unique satellite: Aeolus
The measurement of winds is an essential element of our daily lives. Whether it’s predicting the weather, determining where to place wind farms, constructing airports, or knowing when to evacuate populations during cyclones, understanding winds and having a monitoring system for them is crucial. It is for this purpose that Aeolus was created, the first…

On Sunday, August 12, 2018, an extraordinary mission took place: the launch of the Parker Solar Probe. This probe embarked on a journey into interplanetary space, but its destination is not another planet. No, it’s not aiming for a circular orbit to observe our star from afar. Instead, the Parker Solar Probe is set to…

One day, two launches, fourteen satellites
Last Wednesday, on July 25, 2018, a rather rare event in the aerospace field occurred: Two launches less than 14 minutes apart! Alongside this coincidence, we naturally find ourselves with two payloads on their way to their orbits at the same time, which deserves to be highlighted. What are these payloads, you ask? There were…

American-Russian resupply of the ISS
The International Space Station constantly requires resupply, whether it be provisions for the astronauts, scientific experiments they must conduct, or spare parts to repair faulty elements of this gigantic laboratory. In less than two weeks, the station received two new cargo shipments, totaling no less than 5.5 tons of payload. These two cargos were the…
